I 3 JIM Em flz all Witnesses v Inventor Attorneys 'MEANS iron SHAPINGTHE RnKERgTEnTii or sAWsf 7 To all whom it may concern! I I Be it knownthat I, JQSEPH' M. E iERIoK, a citizen ofthe United States, residing atSalem, in the county of Marion and State of; Oregon, have invented anewandfuseful; Means for Shaping the Baker-Teeth :of

Saws, of which the following specification. gr r c The presentinventlonapperta ns to-saW sets, and aims 'toprovide anovel andTiin; proveddevice of; that o character" adapted especially for use with,crosscutsaws. 3

It is the Object of the inventionto provide an implement jof the natureindicatedl having novel means for" engaging and "accommodating the saw,having novel means i,

for shaping the "rakerteethp having novel means for holdingafile" tofile the points of the ftee'th," and having [other] improved features tothereof.

With the foregoi 1g and other c ots; in view which will appear "as thedescription proceeds, the invention "resides'in the combination andarrangement of parts and in thedetails of construction --hereinafter described and claimed, it" being -nnderstood. I I

In carrying out the invention,,there*is provided an elongated body whichwill'bef e referred to as disposedlongitudinally of the implement, saidbodybeing preferably cast from suitable-metal and having a base plate 2at one end to fit either side offin saw. The plate has the laterallyprojecting wings 3 projecting toward opposite sides, and similarlyprojecting secondary wings 4 between the ends of the body, while thewings 3 arelocatednear the lower end of the body. 'The body 1 isprovided at its other end with an outstanding boss 5 having alongitudinal axis arranged approximately 3 g V sideoftheplate. enhancethe utility andeflioiency p p A i i l i l ap'plled to the saw,;and tofacilitatetheap-g ie. .1 @1311 be e i ste l gitudinal y,oi themselvesand ul y a ou diithebqlt w 12 as gpivots, in orderlthat the hooks l i Iis pl ced against one side of thelsawblade i view, showing a portionSpecifieationof Lttersfiatentfi p te tdju y 2, 1913f QlipplieationfiledMarch15,191 7,'S erlaIi\To.i55,042., l i 5:

points 'offthe saw teeth, the wings 4: are provid'edf with rearwardlyprojectinglugs 17v 5- I threaded;v Thus, when' a' file orielongated.abrasive member 19: is placed'against the H faces of" the bars 7adjacent to their rear f edges',;the screWslS can be screwed towardthefile to clamp it against said bars, as seen through which clampingscrews 18: are

in Fig.2. Then, when themembers are removed or reversed. so that theirhooks 14' will not interfere with the movement of the device, the devicecan be reciprocated. along the saw with the bars 7 "sliding along thepoints of the teeth and with theplate 2 I sliding along one side of theblade. The file 19 is thereby carried along the points of they teeth forfiling the points thereof, and the device can be applied to both sidesof the saw, as will be apparent.

The boss 5 is provided with a'longitudinal 22 has ahead 23 upon itsouter end adapted to be struck by a hammer or' other suitable implement.An adjustable nut'21'is thread- "ed upon the plunger 22 between the head23 and boss 5, and a coiled wire "expansion" spring 25 surrounds theplunger and is confinedbetween the nut 24: and the bottom of the counterbore 21 whereby to move the ;plunger"- 22 outwardly or upwardly byadjusted to regulate tl le tension of the;

i the plunger22 is a swage 26 slidable along spring tension. The spring25 is seated in the counter bore 21, andthe nut'2 1 can be spring.Engaged upon. the inner end of the body or frame 1 between the boss 5and the plate 2; The swage 26 is secured tOLthe plunger 22 "by means ofa set screw 27 or otherwise, and is provided with beveled por "tions"28"to engage the points of the raker tooth 15 andbend them apart andbring themin-to proper position. Thus, when the device is applied to thesaw, a's'indicated in Fig. '3, thehead 23 being struckwith a hammer,will force the swage26 against'the tooth '15 between the points thereof,and the beveled portions 28 wil-l'setthe points of said-teeth, the bladebeing retracted from the toothby the spring 25."

The device is also provided with means for bending the teeth towardopposite sides to setflthem, and for 'this'purp'ose, the body or"frame'member 1 is provided .at that end which "hasthe boss 5, with anoutstanding anvil 29- opposite to the boss. The anvil 29 has a surface30 against which the saw blade or tooth is adapted 'to "rest,ai'id'be-"j you'd the surface 30, the anvil has an inclined surf-ace 31sloping from the surface '30, asf

seen in Fig. 4. Above-the surface 31 is mounted a swage member or head32 having lugs 33 pivoted to lugs 34C upstanding from the anvil 29 Aspring 35 tends to raise or move the member'32 away from the surface 31,andthemember;32 is provided with a beveled portion 36 to move adjacentto and parallel ;with the surface 31 when the 1ne1nber 32 is struck by ahammer or other suitable implement.- By placing the saw upon the anvilwith the pointed end .of the tooth overhanging the surface 31, themember 32 can be struck by a hammer, and will hand the point of thetooth against the surface 31 The saw can'be reversed to bend the teethtoward opposite sides'as will. be ob vious.

Having thus described the invention,.

what is claimed asnew is 1. A deviceof the character described,embodying a body having-a plate, clamping elements carried by saidplate, slotted hold ing members adjustably engaging said elements andhaving portions to engage a saw at oppositesides of a rakertOOth, and aswage movably carried by the body and engageable with r the end ofsaidtooth.

device of the character described, having plate to bear againstone sideof a saw and a memberin a plane, at right angles' to said plate tocontact with the points of the saw teeth, means engageable with-the sawfor positioning said plate relative thereto, and a swage movable againstthe end of one tooth.
